It measures 15 mm (3/4″) when fully grown and has a flattened oval body with long , spindly legs. Both male and female are winged. The colouring is light brown with two dark brown stripes running lengthwise on the thorax (mid-section).

The main attractions for a cockroach are food, water and shelter. For them, almost anything is food, from actual food items, to cloth, to even the glue used for binding books. They can be found in any part of the building, but most prefer damp environments. Most cockroaches are active at night, thus potentially leaving people unaware of their presence.
